I would like to use T1 Ch2 with electric blinds. However there is a major disadvantage as for this purpose, as there must be a possibility do prevent to set state ON on both switches, as this may cause roller's motor damage (simultaneously runs motor up and down).
Conventionally it is solved by 3 way switch which have three states UP/DOWN/OFF.
In case of sonoff there would be niceto have feature(Enable/Disable) which will allow to set ON only one channel at time.
Hi, that is what ITEAD calls "interlocking", what is implemented in the 4CH PRO. There is another feature request asking for that, if you can also vote there it may help to give visibility....
